Study Summary

The purpose of this study is to measure how well monoclonal antibodies work, either alone or in combination, against the virus that causes COVID-19. Study drug(s) will be given to participants with early symptoms of COVID-19. Samples will be taken from the back of the nose to determine how much virus is in the body at various times during the study. Participation could last about 12 or 24 weeks and includes at least 1 visit to the study site, with the remainder of assessments performed in the home, local clinic, or by phone.

Primary Outcome

Percentage of participants with SARS-CoV-2 viral load greater than 5.27 on Day 7. Missing data is estimated using Relevance Sequence Imputation (RSI). RSI is defined as follows: If Day 7 SARS-CoV-2 viral load is missing, then Day 7 will be imputed using data from the first available for Day 5, Day 3, Day 11, or Day 1.
